When using a compatible radar model, the chartplotter
adjusts the sea clutter based on the sea conditions
automatically.
Adjusting Rain Clutter on the Radar Screen
You can adjust the appearance of clutter caused by rain.
Reducing the radar range also can minimize rain clutter
(
The rain clutter setting affects the appearance of
nearby rain clutter and targets more than it affects the
appearance of distant rain clutter and targets. A higher
rain clutter setting reduces the appearance of clutter
caused by nearby rain, but it can also reduce or eliminate
the appearance of nearby targets.
NOTE:
Depending upon the radar in use, the rain clutter
settings configured for use in one radar mode may or
may not be applied to other radar modes or to the radar
overlay.

to decrease or increase the
appearance of nearby rain clutter until other targets are
clearly visible on the radar screen.
Clutter caused by rain may still be visible.
Averaging Multiple Scans on the Radar Screen
You can average the results of multiple scans on the
radar screen. This can be an effective method to filter out
noise and enhances the detection of consistent targets.
Averaging is most effective when using a longer range.

MotionScope™
: Uses the Doppler effect to detect and
highlight moving targets to help you avoid potential
collisions, find flocks of birds, and track weather
formations (
). This option is only available on Fantom
models.
Pulse Exp.
: Increases the duration of the transmit pulse,
which helps maximize the energy directed toward
targets. This helps to enhance the detection and
identification of targets. This option is only available on
xHD radome and xHD2 open array models.
Target Size
: Adjusts the size of targets, by adjusting the
pulse compression processing. Select smaller targets
for a sharp, high resolution radar image. Select larger
targets to display larger echos for point targets, like
boats and buoys. This option is only available on
Fantom models.
Echo Trails
: Enables you to track the movement of
vessels on the radar screen. This option is not available
on xHD open array or HD/HD+ radome models.
VRM/EBL
: Shows the variable range marker (VRM) circle
and the electronic bearing line (EBL) to allow you to
measure the distance and bearing from your boat to a
target object (
).
Guard Zone
: Sets a safe zone around your boat and
sounds an alarm when anything enters the zone
(
).
Timed Transmit
: Helps conserve power by transmitting
radar signals at set intervals.

Source
: Selects the radar source when more than one
radar is connected to the network.
Chart Display
: Shows the chart under the radar image.
When enabled, the Layers menu appears.
Orientation
: Sets the perspective of the radar display.
Crosstalk Rej.
: Reduces the appearance of clutter
caused by interference from another nearby radar
source.
Rotation Spd.
: Sets the preferred speed at which the
radar rotates. The High Speed option can be used to
increase the refresh rate. In some situations, the radar
automatically rotates at the normal speed to improve
detection, for example, when a longer range is selected
or when MotionScope or Dual range is used.
Appearance
: Sets the color scheme, look-ahead speed,
and navigation appearance.
Installation
: Allows you to configure the radar for the
installation, such as setting the front of the boat and
the antenna park position.
Reducing Cross Talk Clutter on the Radar Screen
You can reduce the appearance of clutter caused by
interference from another nearby radar source, when the
cross talk reject setting is on.
NOTE:
Depending upon the radar in use, the cross talk
reject setting configured for use in one radar mode may or
may not be applied to other radar modes or to the Radar
overlay.
